But in fact, fly immunity is highly reproducible! 🎊

~80% of claims could be verified. Moreover, some challenged claims just reflect the field advancing its knowledge/tools.

The lesson: if the tools are good and the research largely exempt from direct translation pressures, science works.

3.5/n
A chart depicting the track of claims into verified, unchallenged, challenged, partially verified, or mixed. Figure 1: Flow of the study. Claims were first classified in five categories based on literature. 45 unchallenged claims were selected to be experimentally tested and classified either as challenged or as verified. We further classify some unchallenged as consistent or inconsistent depending on their consistency with current knowledge.

Paramoeba atlantica as a Natural Intracellular Niche for Vibrios in Marine Ecosystems
Various vibrios can colonise a large vacuole called VCV (Vibrio-containing-vacuole) within Paramoeba atlantica. The VCVs acidify and the vibrios multiply and remain alive inside the VCVs for hours. T...

I'm delighted to share our opinion on #papermills published in Nature. Science is flooded with papers from paper mills.Certain steps can be taken, but this is a challenge that neither universities nor journals are ready to face.Some use paper mills to their advantage.

Les couloirs bruissaient depuis plusieurs semaines d'une nouvelle phase de démantèlement du CNRS menée par Antoine Petit: les labo étoilés sur lesquels se concentreraient les moyens, les autres étant laissés à l'abandon. Ils s’appelleront "keylabs".

Today we report that an engineered skin bacterium, swabbed gently on the head of a mouse, can unleash a potent antibody response against a pathogen. Could lead to topical vaccines that are applied in a cream. @djenetbousbaine.bsky.social led the charge... @natureportfolio.bsky.social 1/55

Frequent Q is how mirror bacterium could persist in nature. Marine Prochlorococcus good example. Little downside in terms of competitiveness + resistant to protists and phages. Net positive growth allows invasion.

See Chapter 8 of technical report here:
purl.stanford.edu/cv716pj4036
Figure 8.2 from technical report on mirror bacteria, showing potential for net population growth and invasion of marine environment by mirror phototrophic bacteria.

Important piece by Gittleman - “It’s impossible to separate human health from health of the natural world. Ecology is the unifying science that integrates knowledge..[the] One Health approach is unlimited, exciting, & necessary for the health of life on our planet” www.pnas.org/doi/10.1073/... 🧪🌎🌐🌾
Photo of the front page of the paper - showing animals and plants and people encircled across the globe - There needs to be more emphasis on the ecological component of One Health as we consider the problems of biodiversity loss, climate extremes, habitat fragmentation, and emerging disease.

Plasmid afficionados: Does anybody know of any chromosomal genes that are required for plasmid conjugation? We have found a few by chance in a recent experiment and I would be really interested to know if there are other examples.

The #Drosophila Immunity Handbook 🧵

This project started as a review with the aim, in some sense, to update Lemaitre and Hoffmann (2007; Ann Rev Imm). Then it kinda... got out of hand. But the reason that happened is because Hannah is amazing.
